The third side wall 11 and the fourth side wall 12 are separated from one another by the central chamber 10 and lie opposite one another in the lateral direction, wherein the third side wall 11 and the fourth side wall 12 are located on both sides of the central chamber 10 in the lateral direction.

[0022] As in the Fig. 1, Fig. 4 and Fig. 5, the second side wall 9 is provided with an opening 13, wherein the opening 13 extends through the second side wall 9 and thus connects the central chamber 10 to the outside environment, so that the rod 7 can rotate out of the central chamber 10. The first opening 13 can extend vertically to the upper end of the second side wall 9 and is in communication with an upper opening 14 of the sleeve 1, described below, so that the upper end of the rod 7 can rotate out on top of the sleeve 1.

[0023] As in Fig. 4 and Fig. 5, the first side wall 8 is provided with a first support section 15, wherein the first support section 15 protrudes from the first side wall 8 in the direction of the central chamber 10. The first support section 15 is provided with a first support surface 16, wherein the first support surface 16 is a concavely curved surface and faces the second side wall 9 or its vertical upper side. A normal emanating from any point of the concavely curved surface points to the second side wall 9 and / or its vertical upper side, i.e. the normal emanating from any point of the concavely curved surface points perpendicular to the second side wall 9 or runs vertically upwards or runs obliquely in a region in which its perpendicular alignment to the second side wall 9 up to its vertical upward extension is possible.

[0024] As in Fig. 6, the rod 7 comprises a fifth side wall 17. With further reference to Fig. 7, the rod 7 can have a rectangular cross-section. The rod 7 can further comprise a sixth side wall 18, a seventh side wall 19, and an eighth side wall 20. The fifth side wall 17, the sixth side wall 18, the seventh side wall 19, and the eighth side wall 20 are connected to one another and thus enclose the rod 7 with a rectangular cross-section. The fifth side wall 17 and the sixth side wall 18 are separated from one another by a central chamber of the rod 7 and lie opposite one another in the longitudinal direction, with the fifth side wall 17 and the sixth side wall 18 being located on either side of the central chamber of the rod 7 in the longitudinal direction. The seventh side wall 19 and the eighth side wall 20 are separated from each other by the central chamber of the rod 7 and are opposite each other in the lateral direction, with the seventh side wall 19 and the eighth side wall 20 being located on both sides of the central chamber of the rod 7 in the lateral direction.

[0025] As in Fig. 6 and Fig. 7, the rod 7 is provided with a second support portion 21. With further reference to the Fig. 8, Fig. 9, Fig. 11 and Fig. 12, the second support portion 21 is provided with a second support surface 22, wherein the second support surface 22 is a convexly curved surface.

[0026] In Fig. 8 to 10, the rod 7 is in a retracted position. In Fig. 11 and Fig. 12, the rod 7 is in a transition process between the retracted position and an extended position. The transition process of the rod 7 from the extended position to the retracted position is the reverse of the transition process from the retracted position to the extended position. The following description of the transition from the retracted position to the extended position can also apply conversely to the transition from the extended position to the retracted position and vice versa.

[0027] As in Fig. 8 and Fig. 9, in the retracted position of the rod 7, the rod 7 is located in the central chamber 10, wherein the rod 7 is partially or completely within the central chamber 10. In the illustrated embodiment, the rod 7 is partially located within the central chamber 10. The fifth side wall 17 faces the opening 13, wherein the fifth side wall 17 is partially insertable into the opening 13. The second support section 21 projects vertically downward from the rod 7, and the second support section 21 projects vertically beyond a lower end of the rod 7, so that the second support surface 22 projects vertically beyond the lower end of the rod 7, whereby the second support surface 22 can come into contact with the first support surface 16 when the rod 7 is extended from the retracted position as described below.In the retracted position of the rod 7, the convexly curved surface of the second support surface 22 faces the first side wall 8 or its vertical underside. A normal emanating from any point on the convexly curved surface points to the first side wall 8 and / or its vertical underside, i.e. the normal emanating from any point on the convexly curved surface points perpendicular to the first side wall 8 or runs vertically downwards or runs obliquely in a region in which its perpendicular alignment with the first side wall 8 up to its vertical downwards course is possible. As a result, the second support surface 22 can slide to match the first support surface 16 when the rod 7 is extended from the retracted position as described below.

[0028] As in Fig. 11 and Fig. 12, the rod 7 rotates in the direction of the opening 13 when the rod 7 is extended from the retracted position, wherein the fifth side wall 17 is mounted on the second side wall 9 at the vertical underside of the opening 13 and the rod 7 rotates about the second side wall 9 at the vertical underside of the opening 13 as a pivot point, and wherein the second support surface 22 is mounted on the first support surface 16 and thereby the second support surface 22 slides along this first support surface 16 under the guidance of the first support surface 16, so that the rod 7 extends out of the opening 13 of the sleeve 1 in a rotating manner and smoothly.

[0029] As in Fig. 4 and Fig. 5, the second side wall 9 can be provided with a third support surface 23 on a vertical underside of the opening 13, wherein the third support surface 23 is a convexly curved surface and faces the first side wall 8 or its vertical upper side. A normal emanating from any point of the convexly curved surface points perpendicularly to the first side wall 8 or runs vertically upwards or runs obliquely in a region in which its perpendicular orientation to the first side wall 8 up to its vertical upward extension is possible. The third support surface 23 can be provided on an opening edge at the lower end of the opening 13 of the second side wall 9 and extends from the opening edge at the lower end of the opening 13 of the second side wall 9 towards an inner wall surface of the second side wall 9. As shown in Fig. 6, the fifth side wall 17 may be provided with a fourth support surface 24. As shown in Fig. 8 and Fig. 9, in the retracted position of the rod 7, the fourth support surface 24 faces the second side wall 9, wherein the fourth support surface 24 lies within the second side wall 9. The fourth support surface 24 can be a plane in which a normal emanating from the fourth support surface 24 points perpendicularly to the second side wall 9. As shown in Fig. 11 and Fig. 12, the rod 7 rotates in the direction of the opening 13 when the rod 7 extends from the retracted position, the fourth support surface 24 is mounted on the third support surface 23 and the fourth support surface 24 rotates on the third support surface 23, so that the rod 7 extends from the opening 13 of the sleeve 1 in a smooth and rotating manner.

[0030] As in Fig. 4 and Fig. 5, the sleeve 1 can be provided with a second limiting groove 25 on one or both sides of the central chamber 10 in the lateral direction. In the illustrated embodiment, a second limiting groove 25 is provided on both sides of the central chamber 10 in the lateral direction, wherein the respective second limiting groove 25 is provided in the third side wall 11 or in the fourth side wall 12. The sleeve 1 is provided at its upper end with the upper opening 14, wherein the second limiting groove 25 extends vertically downwards from an opening edge 27 of the upper opening 14. As shown in Fig. 6 and Fig. 7, a head portion 26 is arranged at the upper end of the rod 7, wherein the head portion 26 is provided with a second limiting element 28, and wherein the second limiting element 28 is located on one or both sides of the rod 7 in the lateral direction. In the illustrated embodiment, a second limiting element 28 is arranged on both sides of the rod 7 in the lateral direction. As shown in Fig. 8 and Fig. 9, the head portion 26 projects laterally beyond the rod 7 in the retracted position, so that the head portion 26 is mounted on the opening edge 27 of the upper opening 14. The second limiting element 29 projects vertically downward from the head portion 26 and is inserted into the second limiting groove 25, wherein the second limiting element 28 is blocked by the second limiting groove 25 to prevent a rotational extension of the rod 7 from the retracted position toward the opening 13 and thus to hold the rod 7 in the retracted position. As shown in Fig. 11 and Fig. 12, when extending the rod 7 from the retracted position, the rod 7 must be moved vertically upward before the rod 7 rotates towards the opening 13. In this way, the head portion 26 is left by the opening edge 27 of the upper opening 14 and the second limiting element 28 is thereby separated from the second limiting groove 25, so that the rod 7 can rotately extend towards the opening 13 and then the rod 7 is rotated towards the opening 13. The second limiting groove 25 and the second limiting element 28 can be configured such that the rod 7 is moved vertically upward by 15 mm to separate the second limiting element 28 from the second limiting groove 25. The stroke of the raised rod 7 is short, so that easy, quick and effort-saving handling is possible.The second limiting groove 25 may have a vertical depth of 15 mm and the second limiting element 28 may have a vertical height of 15 mm.

[0031] As in Fig. 4 and Fig. 5, the second boundary groove 25 can be provided with a first boundary surface 29 and a second boundary surface 30. The first boundary surface 29 faces the first side wall 8 and extends in the vertical direction. The first boundary surface 29 can be a plane in which a normal emanating from the first boundary surface 29 points perpendicularly to the first side wall 8. The second boundary surface 30 is a concavely curved surface facing the second side wall 9 or its vertical upper side. A normal emanating from any point of the concavely curved surface points perpendicularly to the second side wall 9 or runs vertically upwards or runs obliquely in a region in which its perpendicular orientation to the second side wall 9 up to its vertical extension upwards is possible. As in Fig. 6 and Fig. 7, the second limiting element 28 may be provided with a mating surface 31 for the first limiting surface and a mating surface 32 for the second limiting surface. As shown in Fig. 8 and Fig. 9, in the retracted position of the rod 7, the fitting surface 31 for the first boundary surface extends in the vertical direction and bears against the first boundary surface 29, wherein the fitting surface 31 for the first boundary surface can be a plane. The fitting surface 32 for the second boundary surface is a convexly curved surface that faces the first side wall 8 or its vertical underside. A normal that originates from any point on the convexly curved surface points perpendicular to the first side wall 8 or runs vertically upwards or runs obliquely in a region in which its perpendicular orientation to the first side wall 8 up to its vertical extension upwards is possible. The fitting surface 32 for the second boundary surface is mounted on the second boundary surface 30 and bears against the second boundary surface 30.By fitting the fitting surface 31 for the first limiting surface to the first limiting surface 29 and the fitting surface 32 for the second limiting surface to the second limiting surface 30, the second limiting element 28 is stably held in the second limiting groove 25, so that the rod 7 is stably held in the retracted position.

[0032] As in Fig. 4 and Fig. 5, the opening edge 27 of the upper opening 14 may be provided with a chamfer 33 on the second side wall 9. The chamfer 33 provides a slope at a connection point between the opening edge 27 of the upper opening 14 and the second side wall 9. As shown in Fig. 11 and Fig. As shown in Figure 12, during the rotation of the rod 7 toward the opening 13 and its associated rotation from the extended position to the retracted position, the fitting surface 32 for the second boundary surface is mounted on the chamfer 33, wherein the fitting surface 32 for the second boundary surface slides on the slope of the chamfer 33. The fitting surface 32 for the second boundary surface slides obliquely upward under the guidance of the chamfer 33, thus enabling easy, quick, and effortless handling.

[0033] As in Fig. 4 and Fig. 5, the sleeve 1 can be provided with a first limiting groove 34 on one or both sides of the central chamber 10 in the lateral direction, wherein the first limiting groove 34 extends in the vertical direction. In the illustrated embodiment, a first limiting groove 34 is provided on both sides of the central chamber 10 in the lateral direction, wherein the respective first limiting groove 34 is provided in the third side wall 11 or in the fourth side wall 12. As shown in Fig. 6 and Fig. 7, the rod 7 can be provided on one or both sides in the lateral direction with a first limiting element 35, wherein the first limiting element 35 protrudes from the rod 7 in the lateral direction, and wherein the first limiting element 35 protrudes laterally beyond the rod 7. In the illustrated embodiment, the first limiting element 35 is arranged only on one side of the rod 7 in the lateral direction, so that the first limiting groove 34 on one side of the central chamber 10 does not effect any limitation and the first limiting element 35 can be a limiting rod. As shown in Fig. 8 and Fig. 10, either in the extended position or in the retracted position of the rod 7 or during the transition of the rod between the retracted position and the extended position, the first limiting element 35 is always inserted in the first limiting groove 34, wherein the first limiting groove 34 blocks the first limiting element 35 and prevents the first limiting element 35 from being released from the first limiting groove 34, thereby preventing separation of the rod 7 from the sleeve 1 and thus detachment of the rod 7 from the sleeve 1.

[0034] As in Fig. 8 and Fig. As shown in Figure 9, in the retracted position of the rod 7, a longitudinal distance of less than or equal to 1.5 mm can be present between the fourth support surface 24 and the second side wall 9. As a result, the second side wall 9 limits the fourth support surface 24 and prevents the rod 7 from oscillating excessively in the sleeve 1.

[0035] As in Fig. 8 and Fig. 9, in the retracted position of the rod 7, the sixth side wall 19 can face the first side wall 8, wherein the sixth side wall 19 lies within the first side wall 8, and wherein a longitudinal distance of less than or equal to 2 mm can be present between the sixth side wall 19 and the first side wall 8. This ensures that the first side wall 8 limits the sixth side wall 19 and prevents the rod 7 from oscillating excessively in the sleeve 1. Furthermore, it is achieved that the rod 7 moves smoothly in the sleeve 1 during a vertical movement of the rod 7 upwards, so that simple and energy-saving handling is possible.

[0036] As in Fig. 6 and Fig. 7, the rod 7 can be provided on both sides in the lateral direction with a second support section 21. When the rod 7 is rotated out in the direction of the opening 13, the rod 7 is mounted on both sides in the lateral direction with the second support surface 22 on the first support surface 16, thereby enabling stable support. Each second support section 21 protrudes from the rod 7 in the lateral direction, whereby one second support section 21 can protrude laterally beyond the seventh side wall 19 and the other second support section 21 can protrude laterally beyond the eighth side wall 20. There is a lateral distance of less than or equal to 2 mm between the second support section 21 and the sleeve 1. This ensures that the sleeve 1 limits the second support section 21 and prevents the rod 7 from oscillating excessively in the sleeve 1.Furthermore, the rod 7 moves smoothly during a vertical upward movement of the rod 7 and during its rotating extension within the sleeve 1, thus enabling simple and effortless handling. This lateral distance is located between a lateral end face of one second support section 21 and the third side wall 11, as well as between a lateral end face of the other second support section 21 and the fourth side wall 12.

[0037] As in the Fig.As shown in Figures 1 to 5 and 8 to 12, the sleeve 1 can be provided at its lower end with a truncated cone-shaped support leg 36. When several pivoting support legs are stacked and stored, an upper truncated cone-shaped support leg 36 can be inserted into a central chamber 10 of a lower sleeve 1, thereby saving space. The truncated cone-shaped support leg 36 can be provided with a channel opening into the central chamber 10 to facilitate drainage of the central chamber 10 of the sleeve 1.

[0038] The present utility model has so far been disclosed with individual embodiments, which, however, are not intended to limit the present utility model. Any person skilled in the art may make any changes and modifications without deviating from the spirit and scope of the present utility model.

[2] Pivoting support foot according to claim 1, characterized by , that the second side wall is provided with a third support surface on the vertical underside of the opening, wherein the third support surface is a convexly curved surface and faces the first side wall or its vertical upper side; and that the fifth side wall is provided with a fourth support surface, wherein in the retracted position of the rod the fourth support surface faces the second side wall, and wherein when the rod is extended from the retracted position, the fourth support surface is mounted on the third support surface and rotates such that the rod is extended in a rotating manner towards the opening. [3] Pivoting support foot according to claim 2, characterized by that in the retracted position of the rod there is a longitudinal distance of less than or equal to 1.5 mm between the fourth support surface and the second side wall. [4] Pivoting support foot according to claim 1, characterized by, that the sleeve is provided with a first limiting groove on one or both sides of the central chamber in the lateral direction, the first limiting groove extending in the vertical direction; and that the rod is provided on one or both sides in the lateral direction with a first limiting element, wherein the first limiting element protrudes from the rod in the lateral direction, and wherein the first limiting member is inserted into the first limiting groove while the first limiting member is blocked from loosening by the first limiting groove to prevent separation of the rod from the sleeve. [5] Pivoting support foot according to claim 1, characterized by , that the sleeve is provided with a second limiting groove on one or both sides of the central chamber in the lateral direction and with an upper opening, the second limiting groove extending from an opening edge of the upper opening in the vertical direction; and that a head section with a second limiting element is arranged at the upper end of the rod, wherein the second limiting element is located on one or both sides of the rod in the lateral direction, wherein in the retracted position of the rod, the head portion projects laterally beyond the rod, the head portion is mounted on the opening edge of the upper opening, the second limiting element projects vertically downward from the head portion and is thereby inserted into the second limiting groove, while the second limiting element is blocked by the second limiting groove to prevent the rod from extending from the retracted position, and wherein upon extension of the rod from the retracted position, the rod is moved vertically upward to leave the head portion from the opening edge of the upper opening and thereby separate the second restricting member from the second restricting groove so that the rod can rotately extend toward the opening. [6] Pivoting support foot according to claim 5, characterized by that when the rod is extended from the retracted position, the rod is moved vertically upwards by 15 mm to separate the second limiting element from the second limiting groove. [7] Pivoting support foot according to claim 1, characterized by in that the rod further comprises a sixth side wall, wherein in the retracted position of the rod the sixth side wall faces the first side wall, and wherein there is a longitudinal distance of less than or equal to 2 mm between the sixth side wall and the first side wall. [8] Pivoting support foot according to claim 1, characterized by that the rod is provided on both sides in the lateral direction with a second support section, wherein each second support section protrudes from the rod in the lateral direction, and wherein there is a lateral distance of less than or equal to 2 mm between the second support section and the sleeve. [9] Pivoting support foot according to claim 5, characterized by , that the second boundary groove comprises a first boundary surface and a second boundary surface, wherein the first boundary surface faces the first side wall and extends in the vertical direction, and the second boundary surface is a concavely curved surface and faces the second side wall or its vertical upper side; and that the second boundary element comprises a fitting surface for the first boundary surface and a fitting surface for the second boundary surface, wherein in the retracted position of the rod the fitting surface for the first boundary surface extends in the vertical direction and bears against the first boundary surface, wherein the fitting surface for the second boundary surface is a convexly curved surface and faces the first side wall or its vertical underside, and wherein the fitting surface for the second boundary surface is mounted on the second boundary surface and bears against it. [10] Pivoting support foot according to claim 9, characterized by that the opening edge of the upper opening is provided with a chamfer on the second side wall, wherein upon rotation of the rod from an extended position to the retracted position the fitting surface for the second boundary surface is slidably mounted on the chamfer.
